"Gavrilov makes the best attempt I know of to distinguish how long
people could live from how long they actually live - one of the more
difficult
tasks for both biology and statistics... Gavrilov's scholarship is
impressive".
- Professor Nathan Keyfitz, International Institute for Applied Systems
Analysis, Laxenburg, Austria. Mathematical Population Studies, 1991,
vol.3,
No.2, p.161.

"... This book is a highly valuable contribution to the
discipline.
...This book should make scientists take notice of research on aging
and
longevity ... in the former Soviet Union" - Dr. S. Jay Olshansky,
Ph.D.,
University of Chicago, USA. Population and Development Review, 1992,
vol.18,

Chicago, USA. Population and Development Review, 1998, vol.24, No.2,
p.384.

"The Gavrilovs have made a valuable contribution to the study of
life span, and any future work on the subject will have to take account
of the rich contents of this book". - Dr. Vaino Kannisto, Former
United
Nations Adviser on Demography. Population Studies, 1992, vol.46, No.2,
pp. 366-367.

"This book should be read by all members of the profession
interested
in mortality - which should be all members of the profession" - Dr.
H.A.R.Barnett, Institute of Actuaries, UK. J.of The Institute of
Actuaries,
1992, vol.119, Part II, pp.379-381.

"... The reader will benefit enormously from the broadening of
perspective
as a result of exposure to the Gavrilovs' theories on the biology of
life
span" - Dr. Michael Akiyama, University of Michigan, Dearborn, USA.
Human Biology, 1992, vol.64, No.4, pp.630-632.

"The book features quite a bit of demographic theory and
analysis.
It is refreshing" - Professor Michael R.Rose, University of
California,
Irvine, USA. Annals of Human Biology, 1992, vol.19, No.3, pp.320-321.

"It raises lots of interesting questions, … clarifies many
methodological
issues, and lays the groundwork in an entertaining way for future
research."
- Dr. Kenneth Hill, The Johns Hopkins University School of Hygiene and
Public Health, Baltimore, USA. American Journal of Epidemiology., 1994,
vol.139, No.2, p.231-232.

"... Should be read by anyone seriously interested in ageing. ...
You will find this a surprisingly good 'read', and a must for every
library".
- Dr.D.Sebastian Fairweather, Physician, Department of Geriatric
Medicine,
Oxford, United Kingdom. Age and Ageing, 1992, vol.21, No.5, pp.386-387.

"The book is well written, easy to read, and should be of
interest
to a wide spectrum of readers including physicians, biologists,
biochemists,
gerontologists..." - Prof. Robert W.Gracy, University of North
Texas,
USA. Educational Gerontology, 1993, vol.19, No.1, pp.92-93.

"Leonid Gavrilov is a top-flight statistical population
biologist...
The area is important well beyond the confines of biological
gerontology
and extends into politics and social planning. Gavrilov is very good on
just this sort of thing. He has a fresh approach, new ideas, a great
deal
of data not readily available elsewhere." - Dr. Roy. L. Walford,
Professor
of Pathology, UCLA School of Medicine, USA. Mathematical Population
Studies,
1991, vol.3, No.2, p.161.

"This book is directed toward researchers interested in
statistical
patterns and mathematical models of human life span. For students
within
this defined area of research, this text offers a good historical
perspective,
insight into the Russian literature, and insight into the quantitative
analysis of life span" - Dr.Deborah A.Roach, Department of Zoology,
Duke University, Durham, USA. Ecology, 1992, vol.73, No.1, pp.379-381.

"This book is in essence a biostatistical analysis of the
problems
of lifespan, human and animal. ... The literature in many languages had
clearly been well covered, and much has been made of national and other
mortality statistics in this century. ... A useful source book." -
Dr. F.I.Caird, D.M., F.R.C.P., Professor of Geriatric Medicine,
Southern
General Hospital, Glasgow, UK. J.of Clinical and Experimental
Gerontology,

"...Provocative and entertaining reading and can be recommended
to
anyone with an interest in biological aging." - Dr. Douglas E.
Crews,
Department of Anthropology, Ohio State University, USA. Journal of
Cross-Cultural
Gerontology, 1993, vol.8, No.3, pp.281-290.

"It deserves to be read widely. Scientists and physicians who are
interested in the aging of populations or of individuals will be much
more
effective in their work if they become familiar with the subject matter
of this book." - Journal of Orthomolecular Medicine, 1993, vol.8,
No.1,
